Subject Re: tomcat crash ... "unexpected exception"
Date Wed, 23 Jun 2004 13:50:25 GMT
if you're using tomcat in standalone mode, I would recommend
commenting out the jk stuff all together. I noticed your minProcessors
is 100 and max is 500. You must get some serious load, or the usage
pattern is such that an unique user session has lots of requets.

good luck.
